In ages past, this citadel, located not far from the
town of Oakhurst, collapsed into the ground, leaving a huge gash on the
countryside known to locals as the "Dark Ravine." In the years since its
collapse, the citadel became the abode of a number of foul creatures:
kobolds, goblins, and Berak the Druid (known colloquially to the adventurers
as the "Frog Man").
Seeking to find and rescue the Hucrele twins, the party
entered the citadel, battling a gigantic rat named Guthash, finding
mysterious dragon shrines, rescuing the young dragon Calcyrx from the
goblins, ravaging through Goblinville, and giving battle to Berak, his Dark
Tree, and various minions in a vast underground cavern known as the Dark
Grove.
In the period after the party left the Sunless Citadel, the kobolds
pushed for greater dominance over the grounds, as Mauser learned to his
great discomfiture. The citadel also contained an entryway into the
Underdark, which Mauser braved -- fleeing from the enraged Jil du Gal, Eiger and Archangel.
